BUDGET_OPTIMIZER to TARGET_SPEND

[cvit sandeep]

I am currently working in Bid Strategy settings.I cant update Bidstrategy from MANUAL_CPC to BUDGET_OPTIMIZER. From here itself i got that BUDGET_OPTIMIZER is replaced with TARGET_SPEND.

1.In BUDGET_OPTIMIZER we have a field 'enhancedCpcEnabled' to enable enhanced cpc.How can i manage this field if i replace it with TARGET_SPEND?Whether it is posssible to do with BUDGET_OPTIMIZER option?

2.Once we update the Bid strategy from MANUAL_CPC to BUDGET_OPTIMIZER in adword screen ,then we can change the value of bid strategy(BUDGET_OPTIMIZER) through API.But i cant change bid strategy type from one to another(MANUAL_CPC to BUDGET_OPTIMIZER)
